[  This had been posted in net.bugs.4bsd, etc., but the Arnold and I
   both thought it important enough to be published in mod.sources;
   indeed, he had originally sent this to mod.sources, but it got
   lost in the changeover from John to me.  -r$ ]

These patches include mcgill-vision!mouse's bug fix (due to a typo).

Basically, with these patches are installed, /lib/cpp gains two new
capabilities: The #elif found in recent versions of System V and in the
draft ANSI standard, and the ability to recognize C++ // comments,
which start with the // delimiter, and go to the end of the line.

#elif is automatic: it is fast becoming a standard C feature, and I
feel that everyone would want it. // comments require that the new -B
option be given, for their recognition to be turned on. Sites with C++
should modify their CC shell script to call /lib/cpp with this option.
(I chose -B as sort of mnemonic for the BCPL programming language, from
which // was re-instituted.)

Credits: Doug Gwyn of BRL implemented #elif for his System V emulation;
however I typed it in to make the "style" consistent; all typos are
mine. I wrote the // processing code. Enjoy.
